The disgraced Stoke striker saw red for hitting Potters ace Andy Griffin.
And boss Tony Pulis says he will crack down on his hitman.
Pulis said: "Ric raised his hands and you can't condone that. I certainly won't be condoning it."
Fuller blamed Griffin for failing to stop a West Ham goal.
Defender Glen Whelan tried to separate the two.
Ref Michael Jones had a brief exchange with Griffin before giving Fuller his marching orders.
TV pictures then showed Griffin telling Fuller to get off and point to the dressing room.
